Mustanski, Meika A. 1993 Journal 29 E. B. Boracuia - SP The Estação Biológica de Boracuia lies midway between Mogi-Guaçu and Salesópolis. The reserve has aprox. 100 ha and lies within a larger reserve that belongs to SABESP/DAE (= dep de águas e esgotos), of aprox 16,500 ha. It includes the drainage of Rio Claro and the headwater of Rio Guaratuba. Rio Claro is the first affluent of significant size of Rio Tietê. Rio Guaratuba flows down the coastal range towards the Atlantic Ocean. The reserve protects water reservoirs that collect water drinking for the region of the city of São Paulo. E.B. Boracuia lies less than 1 km away from the scarp and 14 km away from the sea, at 850 m elevation. E.B.B. was cited in 1954 as such, before it was a place for growing guineiras (for quinin), since 1938. See Travassos-Filho and Camargo, 1958 in Arg. Zool. Est. S.Paulo 2(1): 1-21 for more information about the reserve and research done there. There are 2 park rangers: Séu Firmino and Antônio, that have been living there for 20 and 10 years respectively. We stayed at the researchers' house. There is a separate building for lab work. Boracuia is one of the most moist places in South America, with annual precipitation about/around 4000 mm. We experienced rainy and cold days
